What Is a Tax Bracket?
If you're confused by how federal income taxes work in the United States, you aren't alone. The U.S. uses a progressive tax system with seven federal tax brackets: 10%, 12%, 22%, 24%, 32%, 35%, and 37%.
A "tax bracket" simply defines the rate at which a specific portion of your income is taxed. The most common misconception is that moving into a higher tax bracket means all your income is taxed at that new, higher rate. This is entirely false. In reality, you only pay the higher rate on the income that falls within that specific bracket.

2026 Federal Income Tax Brackets
The IRS adjusts federal tax brackets each year for inflation. Here are the expected brackets for single filers in 2026 (assuming standard inflationary adjustments from 2025):
- 10%: $0 – $11,600
- 12%: $11,600 – $47,150
- 22%: $47,150 – $100,525
- 24%: $100,525 – $191,950
- 32%: $191,950 – $243,725
- 35%: $243,725 – $609,350
- 37%: Over $609,350
Note: If you are Married Filing Jointly, these bracket thresholds are roughly double the single filer limits.
Marginal Rate vs. Effective Rate: What’s the Difference?
When people say, "I'm in the 22% tax bracket," they are referring to their marginal tax rate. Here is the critical difference you need to understand:
Marginal Tax Rate
Your marginal tax rate is the highest bracket your income reaches. It is the rate you pay on the very last dollar you earn. If you earn an extra $1,000 next year, it will be taxed at your marginal rate.
Effective Tax Rate
Your effective tax rate is the average percentage of your total income that you actually pay in taxes. Because the U.S. uses a progressive system, your first dollars are always taxed at 10%, the next chunk at 12%, and so on. As a result, your effective tax rate is always lower than your marginal tax rate.
A Real-World Example
Let's look at the math for a single filer earning $85,000 a year taking the standard deduction (currently $14,600).
First, subtract the standard deduction from gross income to find the taxable income: $85,000 - $14,600 = $70,400 taxable income.
Now, let's pass that $70,400 through the brackets:
- The 10% Bracket: The first $11,600 is taxed at 10%. ($11,600 × 0.10) = $1,160
- The 12% Bracket: The income from $11,600 to $47,150 (which is $35,550) is taxed at 12%. ($35,550 × 0.12) = $4,266
- The 22% Bracket: The remaining income ($70,400 - $47,150 = $23,250) falls into the 22% bracket. ($23,250 × 0.22) = $5,115
Total Federal Tax: $1,160 + $4,266 + $5,115 = $10,541
In this example, the taxpayer is in the 22% marginal bracket. But their effective rate is just 12.4% ($10,541 ÷ $85,000). That's a massive difference!
Standard Deduction vs. Itemized Deductions
Before your income passes through the tax brackets, you get to shrink it by taking deductions. Taxpayers must choose between the Standard Deduction and Itemizing.
The Standard Deduction is a flat, automatic reduction in your taxable income offered by the IRS. For a single filer, it is $14,600. For married couples filing jointly, it is $29,200.
Itemized Deductions are specific, qualifying expenses you incurred during the year, such as mortgage interest, state and local taxes (capped at $10,000), large charitable donations, and significant medical expenses. You should only itemize if the sum of these expenses is greater than your standard deduction. Today, about 90% of Americans take the standard deduction because it is higher.
How to Legally Lower Your Tax Bill
Want to shrink your taxable income and drop into a lower marginal bracket? Here are the most effective strategies:
- Maximize your 401(k) or 403(b): Contributions are made with pre-tax dollars, immediately lowering your taxable income. For 2026, the limit is likely to remain around $23,500 ($31,000 if you are 50 or older).
- Contribute to an HSA: If you have a high-deductible health plan, a Health Savings Account offers a triple tax advantage. Contributions are tax-deductible, growth is tax-free, and withdrawals for medical expenses are tax-free.
- Use a Traditional IRA: Depending on your income and workplace plan availability, you may be able to deduct up to $7,000 in Traditional IRA contributions.
- Harvest Capital Losses: If you have investments that have lost value, selling them can allow you to deduct up to $3,000 against your ordinary income. (You can calculate your investment taxes with our Capital Gains Tax Calculator.)
What This Means For You
Understanding the difference between marginal and effective tax rates is crucial. It prevents you from fearing a raise or bonus just because it might push you into a "higher bracket." Remember: only the new money is taxed at the higher rate; your current income stays right where it is.
